  • Command-line input causes SyntaxError

    - by coson
    Good Day, I have a simple Python question that I'm having brain freeze on. This code snippet works. But when I substitue "258 494-3929" with phoneNumber, I get the following error below: # Compare phone number phone_pattern = '^\d{3} ?\d{3}-\d{4}$' # phoneNumber = str(input("Please enter a phone number: ")) if re.search(phone_pattern, "258 494-3929"): print "Pattern matches" else: print "Pattern doesn't match!" ####################################################### Pattern does not match Please enter a phone number: 258 494-3929 Traceback (most recent call last): File "pattern_match.py", line 16, in <module> phoneNumber = str(input("Please enter a phone number: ")) File "<string>", line 1 258 494-3929 ^ SyntaxError: invalid syntax C:\Users\Developer\Documents\PythonDemo> By the way, I did import re and tried using rstrip in case of the \n What else could I be missing? Thanks in advance.

  • Why does Rake task enhancement differ between my local environment and when deploying to Heroku Cedar?

    - by John Bachir
    I have this in lib/tasks/foo.rake: Rake::Task["assets:precompile"].enhance do print ">>>>>>>> hello from precompile" end Rake::Task["assets:precompile:nondigest"].enhance do print ">>>>>>>> hello from precompile:nondigest" end When I run rake assets:precompile locally, both messages are printed. When I push to heroku, only the nondigest message is printed. However, according to the buildpack, the push is executing the exact same command as I am locally. Why does the enhancement to the base assets:precompile case not work on heroku but does work locally?

  • How can I work around the fact that in C++, sin(3.14159265) is not 0?

    - by Adam Doyle
    In C++, const double Pi = 3.14159265; cout << sin(Pi); // displays: 3.58979e-009 it SHOULD display the number zero I understand this is because Pi is being approximated, but is there any way I can have a value of Pi hardcoded into my program that will return 0 for sin(Pi)? (a different constant maybe?) In case you're wondering what I'm trying to do: I'm converting polar to rectangular, and while there are some printf() tricks I can do to print it as "0.00", it still doesn't consistently return decent values (in some cases I get "-0.00") The lines that require sin and cosine are: x = r*sin(theta); y = r*cos(theta); BTW: My Rectangular - Polar is working fine... it's just the Polar - Rectangular Thanks! edit: I'm looking for a workaround so that I can print sin(some multiple of Pi) as a nice round number to the console (ideally without a thousand if-statements)

  • Error Using PDCurses: Cannot Open File Libc.C

    - by cam
    I'm getting the error: 1>LINK : fatal error LNK1104: cannot open file 'LIBC.lib' Here's my source code: #include <curses.h> int main() { initscr(); /* Start curses mode */ printw("Hello World !!!"); /* Print Hello World */ refresh(); /* Print it on to the real screen */ getch(); /* Wait for user input */ endwin(); /* End curses mode */ return 0; } I've configured the PDcurses library properly (added to Additional Include libraries, added folder to Additional Library Directories). I've looked around for a bit, and I've tried adding Libc.C to the 'Ignore Library' list, which in turn causes about 150 errors. Not sure what to do from here.

  • RNDC fails: permission denied

    - by pawz
    Named works great. It creates a pid in /var/run/named/named.pid as expected. It is listening on port 953 as shown by the log: Apr 20 14:42:38 guchuko named[9115]: command channel listening on 127.0.0.1#953 But whenever I try to run "rndc reload" I get: rndc: 'reload' failed: permission denied What file is it being denied permission to ? It doesn't log anything so I don't know why it's not working. I've compiled bind 9.4-ESV-R1 from source and I've patched it with the mysql mod. my named.conf: options { directory "/var/bind"; forwarders { 203.82.213.101; 203.188.144.1; }; listen-on-v6 { none; }; listen-on { 127.0.0.1; 192.168.0.6; }; pid-file "/var/run/named/named.pid"; }; logging { channel simple_log { file "/var/log/named.log" versions 3 size 5m; severity debug 5; print-time yes; print-severity yes; print-category yes; }; category default { simple_log; }; }; zone "."

  • Python beginner, strange output problem

    - by Protean
    I'm having a weird problem with the following piece of code. from math import sqrt def Permute(array): result1 = [] result2 = [] if len(array) <= 1: return array for subarray in Permute(array[1:]): for i in range(len(array)): temp1 = subarray[:i]+array[0]+subarray[i:] temp2 = [0] for num in range(len(array)-1): temp2[0] += (sqrt(pow((temp1[num+1][1][0]-temp1[num][1][0]),2) + pow((temp1[num+1][1][1]-temp1[num][1][1]),2))) result1.append(temp1+temp2) return result1 a = [['A',[50,1]]] b = [['B',[1,1]]] c = [['C',[100,1]]] array = [a,b,c] result1 = Permute(array) for i in range(len(result1)): print (result1[i]) print (len(result1)) What it does is find all the permutations of the points abc and then returns them along with the sum of the distances between each ordered point. It does this; however, it also seems to report a strange additional value, 99. I figure that the 99 is coming from the computation of the distance between point a and c but I don't understand why it is appearing in the final output as it does.

  • Perl throws an error message about syntax

    - by Ben Dauphinee
    So, building off a question about string matching (this thread), I am working on implementing that info in solution 3 into a working solution to the problem I am working on. However, I am getting errors, specifically about this line of the below function: next if @$args->{search_in} !~ /@$cur[1]/; syntax error at ./db_index.pl line 16, near "next " My question as a perl newbie is what am I doing wrong here? sub search_for_key { my ($args) = @_; foreach $row(@{$args->{search_ary}}){ print "@$row[0] : @$row[1]\n"; } my $thiskey = NULL; foreach $cur (@{$args->{search_ary}}){ print "\n" . @$cur[1] . "\n" next if @$args->{search_in} !~ /@$cur[1]/; $thiskey = @$cur[0]; last; } return $thiskey; }

  • Copy and Store LPTSTR in class causes crash

    - by Jake M
    I am attempting to copy a LPTSTR and store that string as a member variable in an object. But my attempts to copy the LPTSTR seem to fail and when I go to access/print the value of the copied LPTSTR I get a program crash. Is it possible to copy a LPTSTR and store it in my class below or is it better to just use a TCHAR*? class Checkbox { private: LPTSTR text; HWND hwnd; public: Checkbox(HWND nHwnd, LPTSTR nText) { lstrcpy(checkText, text); } void print() { // Causes a crash MessageBox(hwnd, text, text, MB_OK); } };

    - by Jonas
    I'm trying to print Invoices in a Java Swing applications. I do that by extending Printable and implement the method public int print(Graphics g, PageFormat pf, int page). I would like to draw strings in columns, and when the string is to long I want to clip it and let it end with "...". How can I measure the string and clip it at the right position? Some of my code: Font headline = new Font("Times New Roman", Font.BOLD, 14); g2d.setFont(headline); FontMetrics metrics = g2d.getFontMetrics(headline); g2d.drawString(myString, 0, 20); I.e How can I limit myString to be max 120px? I could use metrics.stringWidth(myString), but I don't get the position where I have to clip the string. Expected results could be: A longer string that exc... A shorter string. Another long string, but OK

  • How to make a sample file with Handbrake

    - by MaxMackie
    I want to test a couple things with my encode before I encode the whole file. Is there a way for me to make a sample file (30 seconds long or something like that) that I can analyse using different applications (not just the built in sample preview). By the way, I'm using the OSX Handbrake. Alternatively, the question can be stated as: "Where does handbrake store the short sample video files after creating them?"

  • How can I prevent users from taking screenshots of my application window?

    - by Midday
    What are some methods to prevent screenshots from being taken, if any? I've considered setting the "Print Screen" button as a hotkey, which makes the window fuzzy. However, there would be the problem of other 3rd party screenshot tools. How can I prevent their use? Why would I want such a thing? The idea is to create a chat client which you can't share the chatted information with others, not by copy & paste nor by print screen... Looking for general ideas or suggestions rather than actual code.

  • Python and Plone help

    - by Grenko
    Im using the plone cms and am having trouble with a python script. I get a name error "the global name 'open' is not defined".

  • How to get the running of time of my program with gettimeofday()

    - by Mechko
    So I get the time at the beginning of the code, run it, and then get the time. struct timeval begin, end; gettimeofday(&begin, NULL); //code to time gettimeofday(&end, NULL); //get the total number of ms that the code took: unsigned int t = end.tv_usec - begin.tv_usec; Now I want to print it out in the form "**code took 0.007 seconds to run" or something similar. So two problems: 1) t seems to contain a value of the order 6000, and I KNOW the code didn't take 6 seconds to run. 2) How can I convert t to a double, given that it's an unsigned int? Or is there an easier way to print the output the way I wanted to?

  • Multiprocessing Bomb

    - by iKarampa
    I was working the following example from Doug Hellmann tutorial on multiprocessing: import multiprocessing def worker(): """worker function""" print 'Worker' return if __name__ == '__main__': jobs = [] for i in range(5): p = multiprocessing.Process(target=worker) jobs.append(p) p.start() When I tried to run it outside the if statement: import multiprocessing def worker(): """worker function""" print 'Worker' jobs = [] for i in range(5): p = multiprocessing.Process(target=worker) jobs.append(p) p.start() It started spawning processes non-stop, without any way of to terminating it. Why would that happen? Why it did not generate 5 processes and exit? Why do I need the if statement?

  • Turn icon previews off globally in Mac OS X Snow Leopard

    - by Frederik
    When connecting to network drives (e.g. using ExpanDrive) every operation takes a long time. I've discovered this is due to the Finder trying to render an icon preview of every music file and PDF it encounters. Over the network, this can take a long time. I know I can turn off icon previews on a per-folder basis using the "View Options" dialog. Is it possible to change these settings globally?

    I am using use Win32::Process for my application run as below. It runs fine, but I did not get any way to get the output to a .txt file.

  • Silverlight4 Printing Question

    - by hallgato.attila
    Hello everyone! I'm having a problem with printing. Is it possible to print a (customized) DataGrid which doesn't fit the page? a) Using a ViewBox to make it fit one page. My problem here is that I can get the PrintableArea.Width and PrintableArea.Height in the PrintPage EventHandler, from the PrintPageEventArgs, but in that Event Handler I can't set the size of an UIElement before it gets printed. b) Multiple pages. Is it possible somehow to print the whole DataGrid, even the parts which are not visible (don't fit the page) and to somehow make the PrintableArea only a part of the DataGrid?

  • Add xcode-select to PATH vs. Install Xcode Command Line Tools?

    - by MattDiPasquale
    Now with Xcode 4.5, is it OK to just add the following line to my ~/.bash_profile rather than installing the Xcode Command Line Tools? export PATH="$PATH:`xcode-select -print-path`/usr/bin:`xcode-select -print-path`/Toolchains/XcodeDefault.xctoolchain/usr/bin" Note: Xcode says the following about Command Line Tools: Before installing, note that from within Terminal you can use the XCRUN tool to launch compilers and other tools embedded within the Xcode application. Use the XCODE-SELECT tool to define which version of Xcode is active. Type "man xcrun" from within Terminal to find out more.
